✦ Synopsis
When HRP was injected i.v. in rabbits and guinea pigs, a rapid fall in the number of circulating platelets and the concentration of 5 HT occurred. Platelet aggregates were trapped in lung capillaries. The aggregation was reversible and the return of platelets to the circulation concomitant with a rise in blood 5 HT concentration.

Blood levels of 5-hydroxytryptamine (5-HT) and epinephrine are increased in conditions such as severe hypoxia, and hypovolemic or septic shock. The effect of these agents, which influence the blood coagulation system, were studied in vitro on platelets from newborns. 5-HT was determined in platelets
The presence of 5-hydroxytryptamine (5-HT), as well as its precursor (5-HTP) and metabolite (5-HIAA), were biochemically determinated in the trigeminal ganglion of the guinea pig and rat. The distribution of 5-HT in the ganglion and in its posterior root was studied using both indirect immunofluores
